Eastern vs Mexican vs Slough Amerwing

Three amberwing species (Perithemis sp.) breed in Arizona: the Mexican, Slough, and Eastern Amberwings. All are characterized by small size, rounded wings, and generally orange color. The Mexican Amberwing is widespread throughout the southwestern half of the state whereas the distribution of the other two species, in particular the Slough Amberwing, is restricted to the southeast corner of Arizona (Paulson 2009, but see News for a 2010 extralimital record of the Slough Amberwing).
